Did You Know?

With the #CPASLOINENTRAIN app, learn as much about the history of Ile-de-France monuments as about the lives of great men.

Did you know for example that Honoré de Balzac lived near the current RER C, at the avenue du Pont Kennedy in Paris? His house on rue Raynouard is now a museum. The famous writer lived there from 1840 to 1847 and wrote some of his most famous novels there.

The Queen's dairy, located in Rambouillet, welcomed Louis XVI and Marie-Antoinette who liked to be there when he came to hunt? Or that it was in Valmondois, at the house of the mill, that Jean de la Fontaine allegedly wrote his fable "The miller, his son and the donkey"?


To literally immerse yourself in history, the #CPASLOINENTRAIN app offers you thirty before-and-after comparative photos on the major monuments of Paris: the Opéra Garnier, the Eiffel Tower, Orsay station, etc. Rediscover old photos of the monuments you admire and compose original photos yourself, superimposing views of the past and present.
